If you're concerned about genetic diseases, then frame it like that. I don't see why race in particular is so much of an issue when any race has its own set of genetic quirks to worry about. If you stay within your own race, aren't you more likely to have a kid with genetic problems that are specific to your race? It's a problem that seems kind of unavoidable.
And, if you generally choose your potential partners based on what genes they may-or-may-not pass down to your future children then that's one thing. But, I must ask, what else goes into this sort of decision? Would you avoid dating someone who's colorblind or has dandruff -- not because you care about it on them but because you're worried about your future kids? Would you not date someone who has ADHD or family members with ADHD? Would you want to make sure that your partner's family doesn't seem to have any history of Alzheimer's or an increased risk of cancer?
The list could go on and on. With any partner, there are lots of things you run the risk of your kinds inheriting -- in varying degrees of severity. Point is, I don't think it should be a race issue. If you're really concerned about what your kids might inherit, then there's a lot more to look at than race.
For one, I'm not saying me. I didn't get pregnant thinking "Well gee, my husband is white. I'm white. So that narrows down my baby's chances of getting....." I am saying that there ARE people out there who are concerned with diseases and illnesses, and it's not reliant on just race.
You can't take offense for someone's reproductive choices. If someone wants their child to be the same race as them, that is their personal choice, and no one has the right to judge them for it. You're not going to be taking care of that child, they are, and if they think that it'll be better to have a baby that is one race, than that's entirely their choice. Telling people they're wrong because they feel that was it just play ignorant. People who feel that way have their reasons, and you don't know enough about their story to really judge them. I for one wouldn't have had a mixed baby because 1.) The area I lived in would have made it difficult for them to be accepted. 2.) My family would not have accepted them, and while you may fel that isn't important, try raising a baby alone without any family support.
Why would I put a baby through a life where they would never be accepted by their own family?
I was in a long term relationship with a black guy, and there was a lot of things that turned me off of the idea of having a child with him, and race did play a part in it, but it was my race. Seeing how his friends and family treated me and listening to all the 'The white girl this....' and 'The white princess....' that, I would have never brought a kid into that. My ex's uncle was married to a white woman, and his kids were the outcasts of the family. They were teased and ridiculed at every single family get together, and always considered beneath the other kids who were black. No one wants to see their kids subjected to that. Now if my ex's family had been more accepting, and he and I had gotten to the point where children could be considered, than I might have thought about it. but I still wouldn't have gone through with it because of the reasons I stated earlier. My family would not have been accepting, and whether people like it or not, I do have a close relationship with most of my family and I would not want to ruin that. Plus, living in a predominantly white community, I knew that they would have had an extremely difficult time with acceptance.
Everyone is also overlooking the fact that in spite of the fact we've evolved past the point of cavemen, humans are still instinctual creatures. We are attracted to the people who we believe will give us the strongest offspring (At least if you believe in Darwinism and all that jazz.) If a person is against the idea of having an interracial baby, it could be that their instincts simply do not deem a mixed child as the strongest possible offspring. You can't argue with the programming inside your mind. You can try, but in the end it's going to win out.
